This video shows the progress made on Cocoa Radio since the last video. The spectrum that is visualized in the waterfall and graph is AFTER the downconversion mixer and FIR filter. As I move the red line (software tuning) around on the display, it changes the tuning of the downconverter, and you can see the spectrum change. Also, when I change the IF bandwidth, you can see the effects of the filtering. There’s still quite a bit of work to be done, but these results are encouraging. – Source
